Know Before You Go
There are two main ways to get to Sado Island and the festival grounds. The first is traveling by bullet train from Tokyo to Joetsu Myoko Station, taking a bus or taxi from there to Naoetsu Port, and then catching a high-speed ferry to Ogi. This will allow you to get directly to the part of Sado where most of the festivities are centered.
Alternatively, you can travel by bullet train from Tokyo to Niigata Station, take a bus or taxi to Niigata Port, and take a car ferry or jetfoil to Ryotsu. From there it takes about one hour by car to reach the festival grounds in Ogi.
